Answer:
$1.47.
Explanation:
We have been given an equation
that can be used to predict the price per pound of white bread where x is the number of years since 1983.
Let us find the number of years from 1983 to 2015 by subtracting 1983 from 2015.
![x=2015-1983](https://img.qammunity.org/2020/formulas/mathematics/high-school/95ddq0xg2omyfw3n8x4zba583uh66xhksj.png)
![x=32](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jpdb3so0heymvezdk2e87997ia97cwi5uu.png)
Let us substitute x=32 in our given equation to find the price of per pound of white bread in the year 2015.
![y=0.03*32+0.51](https://img.qammunity.org/2020/formulas/mathematics/high-school/1zo2rca4fio92awe972m9p8gjmexq270we.png)
![y=0.96+0.51](https://img.qammunity.org/2020/formulas/mathematics/high-school/q0y30gjhfsgmp3lxh4jsb4zp494lc88ck2.png)
![y=1.47](https://img.qammunity.org/2020/formulas/mathematics/high-school/q0vitskaaaed1ej0noqbjvoyq2azy7yq13.png)
Therefore, the price of per pound of white bread in the year 2015 will be $1.47.
